To all whom t may concern.' v

Be it known that l, WILLIAM vEDWARD GORDON, of the city of Winnipeg, inthe Province of Manitoba, Canada, have invented certain new and usefulImprovements in Spring Winding or Stressing Mechanism forTalking-Machines, of 'which the following is the specification:- Y A Theinvention relates to'improvements in talking machines and particularlyto means or drivingthe disk table and the principal object 'of theinvention is to provide a driving motor embodying av helical or spiralspring 'asa source of power and which is connected-'by suitable gearingtothe turntable spindle and is arranged vsuch-that when thek springfisextended it 'will `operate the spindle to drive'the table. Y

chine with theside brokenaway toV expose further object is to provide ahand lever byi'which the spring can be lfully exltended in one pull ofYthe 'lever i'f'desired,

and arranged also such that the lever can be ratcheted 'step' by stepshould'the pull prove excessive such-as for a child!v VA further objectof the inventionis to provide hand lever having a' back andforwardmovement-.and connected v'vith the motor of thetalking machine and toenergize the motor in the forward pulling ofthe-lever. f f f A stillJfurther' object is to `associate with the lever Sand the turntable a:brake mechanism adapted to` stop the turntable when engaged by thelever.- v.

"A 'still ur'therobject isv to provide a cheap, durable and efficientmotor of lthe above kindand 'to arrangethe 'parts such that they can bereadily installed'and assembled." 1 A With the'above morev important'objects in view ,theinvention .consists essentially in the arrangementvand' constructionv of partsy 'hereinafter more particularly describedand later pointed, out; m'the appended claims,

2. In talking' machine, the combination with the turntable spindle, of ahelical springphaving one end fast, a pivoted lever, a chain connectingthe lever with the other end of the spring, a suitably mounted drivingshaft,

on the shaft and carrying the chain, a ratchet and ratchet wheel forcoupling the chain wheel to the shaft when rotated in one direction anda driving connection between the shait and the spindle.

3. In a talking machine, the combination with the turntable spindle, ofa helical spring having one end fast, a pivoted lever, a chainconnecting the lever with the other end Vof the spring, a suitablymounted driving shaft, a chain wheel rotatably7 mounted on the shaft andcarrying .the chain, a ratchet and ratchet wheel for' coupling the chainwheel to the shaft when rotated in one direction, a countershaftadjacent the spin'- dle, a worm and worm wheel drive between thecountershaft and the spindle and a driving connection between thedriving shaft and the countershaft.

4. Ina talking machine,

with a turntable,'a spring motor and a re-l ciprocating lever forenergizing the motor,

a chain wheel rotatably mounted.

5. In a talking machine, with a turntable, a spring motor and a pivotedmotor energizing lever having a forward and backward movement, of aturntable'brake actuated by the lever as it approaches its rearmostpoint of travel.

6. In a talking machine, the combination with a turntablea spring motorand a pivoted motor energizing lever having a forward and backwardmovement, of a pivoted brake lever havin one end crossing the path oftravel of the ormer lever and the other end fitted with a brake shoeengageable with the periphery of the turntable. v 7.
